It's hard to believe that anyone who owns an iPhone, iPod Touch, or iPad has not at one time utilized the music playing functionality that helped make Apple's pocket sized lineup popular. Music Tempo, by developer Brock Haymond, realizes this. Instead of inventing a new wheel, Haymond has chosen to utilize the already polished iOS music player design, and simply add additional functionality directly to the player.

Through Haymond's Music Tempo app, tempo change functionality is plugged directly into familiar functionality, providing a much missed feature for performers, workout aficionados, and DJ wannabes alike. The ease of use is only limited to the knowledge base one has with already existing technology.

Features include a tempo change without pitch adjustment, great sound quality that eliminates audio artifacts of any kind, mirrored audio file support to already existing technology on the iOS, and on the fly transcoding for quick and easy use of any file type.
